Today (27 January) marks the International Day of Holocaust Remembrance, an occasion to commemorate the victims of the World War II Nazi German regime.
You can watch a commemoration event at Auschwitz from 4 pm in the video player, above.
The Nazis systematically murdered an estimated six million Jews and an additional 11 million people — including members of the Roma and Sinti communities and LGBT+ people, and opponents of the regime — during the war.
The date was chosen by the United Nations General Assembly in 2005 to commemorate the date that Auschwitz concentration camp was liberated by the Red Army in 1945.
